Operational parameters. Life time recommendations
Linde high pressure units are designed for excellent reliability and long service life. The actual service life of a hydraulic unit is
determined by numerous factors. It can be extended significantly through proper maintenance of the hydraulic system and by using
high-quality hydraulic fluid.
Beneficial conditions for long service life
>>Speed
lower continuous maximum speed
>>Operating pressure less than 300 bar ∆p on average
>>Max. pressure
only at reduced displacement
>>Viscosity
15 ... 30 cSt
>>Power
continuous power or lower
>>Purity of fluid
18/16/13 in ac. with ISO 4406 or better
Adverse factors affecting service life
>>Speed
between continuous maximum speed
and intermittent maximum speed
>>Operating pressure more than 300 bar ∆p on average
>>Viscosity
less than 10 cSt
>>Power
continuous operation close to max. power
>>Purity of fluid
lower than 18/16/13 in acc. with ISO 4406
Operational parameters. Filtration
In order to guarantee long-term proper function and high efficiency of the hydraulic pumps the purity of the pressure fluid must
comply with the following criteria according to Linde Works Standard WN 51 210. High purity oil can extend the service time of
the hydraulic system significantly.
>>For reliable proper function
and long service life
18/16/13 in accordance with ISO 4406 or better
>>Minimum requirements
20/18/15 in accordance with ISO 4406
>>Commissioning
The minimum purity requirement for the hydraulic oil is based on the most sensitive system
component. For commissioning we recommend a filtration in order to achieve the required
purity.
>>Filling and operation of hydraulic systems
The required purity of the hydraulic oil must be ensured during filling or topping up. When
drums, canisters or large-capacity tanks are used the oil generally has to be filtered. We
recommend the implementation of suitable measures (e.g. filters) to ensure that the
required minimum purity of the oil is also achieved during operation.
>>International standard
code number according to ISO 4406 purity class according to SAE AS 4059
18/16/13
corresponds to 8A/7B/7C
20/18/15 9A/8B/8C
Filters
Units of the HPV-02 series can be equipped with a pure charge pressure manifold or with a combined charge pressure and filter
flange manifold. The following filter sizes are available, depending on the rated size of the unit. Further details about the mounting
of the charge pressure manifold see section "Dimensions. Modular System".

Operational parameters. Pressure Fluids and mounting orientation
In order to ensure the functional performance and high efficiency of the hydraulic pumps the viscosity and purity of the operating
fluid should meet the different operational requirements. Linde recommends using only hydraulic fluids which are confirmed by
the manufacturer as suitable for use in high pressure hydraulic installations or approved by the original equipment manufacturer.
Permitted pressure fluids
>>mineral oil HLP to DIN 51 524-2
>>biodegradable fluids in accordance with ISO 15 380 on request
>>other pressure fluids on request
Linde offers an oil testing service in accordance with VDMA 24 570 and the test apparatus required for in-house testing. Prices
available on request.

In order to be able to select the right hydraulic fluid it is necessary to know the working temperature in the hydraulic circuit. The
hydraulic fluid should be selected such that is optimum viscosity is within the working temperature range (see tables).
The temperature should not exceed 90 °C in any part of the system. Due to pressure and speed influences the leakage fluid
temperature is always higher than the circuit temperature. Please contact Linde if the stated conditions cannot be met in special
circumstances.

Mounting orientation
The preferred mounting orientation is generally horizontal. Special pump configurations for vertical mounting with the drive shaft
pointing either upward or downward are available for selected rated sizes and have to be requested separately.
For further information concerning the installation of the unit please refer to the operating instructions manual.

Torque transmission.
Depending on the selected components, different torques may be transferred. Please ensure that the load transfer components
such as mounting flange, PTO-through shaft and additional pumps are designed adequately. Our sales engineers will be pleased
to provide design advice.

Gear pumps.
Two types of gear pumps are available: internal gear pump IGP and external gear pump EGP. The possible combinations of and
with IGP and EGP are determined by the PTO option and the permitted shaft torque. Both types can be used as charge pump for
the main circuit or the control and cooling circuit. The allowable pressure at the suction port is between 0.8 bar (abs.) and 3.0 bar
(abs.). The charge pressure relief valves for the rated sizes 55-135 are integrated in the port plate housing, and for the rated sizes
165-280 in the charge pressure manifold of the HPV-02.

Controls.
The modular control concept with standardised interface enables quick selection and adaptation for different customer and system requirements with mechanical, hydraulic or electronic control. All Series 02-controls feature an upstream signal circuit that
is adapted to the respective control, and a standardised and load-independent servo control for simple and constantly available
machine or vehicle control.

Controls. Control accuracy
All Series 02-pump controls result in the same machine response for identical motion commands, irrespective of the control type.
Corrective action by the operator is no longer required. The reliable control of the pump can easily be integrated into any kind of

Setting the maximum displacement
Special control elements deal with functions such as torque control or pressure cut-off regulation. Controls with pressure cut-off
regulation (PCO) reduce pump flow when the cut-off pressure is reached. Because system pressure is maintained at low flow, the
power consumption and thermal balance of the system are optimised.

and can be combined with a fixed, variable or regulating hydraulic motor. The control-specific data is independent of the nominal
pump size.
M1R Mechanical control
Flow direction
By turning the control lever the pump flow rate and direction of flow are controlled via a cam plate. The flow direction of the fluid
depends on

Controls. Mechanical-hydraulic M
The cam plate offers a large control angle with progressive control characteristic and a wide neutral range. The resulting high
resolution for movements from the neutral range (and vice versa) enables precise manoeuvring. Reliable and robust control of the
displacement volume is achieved through position feedback.

Controls. Hydraulic H
The HPV-02 H1 features hydraulic control with a wide pilot pressure range for improved machine control. It can be combined with a
fixed, variable or regulating hydraulic motor. The data is specific for hydraulic controls, and independent of the nominal pump size
and pressure cut-off regulation PCO, unless specified otherwise otherwise (see section Controls. Control accuracy).

By an external hydraulic signal input at the pilot pressure ports (Y, Z) the pump flow rate and direction of flow are controlled. The

Controls. Electro-hydraulic E1 and E5
The HPV-02 E1 has two proportional solenoids and through the upstream signal circuit it combines the flexibility of electronic vehicle management with the reliability of a pump control marked by its high operational availability. Precise and simple. Identical commands always call for the same response in the machine, so no corrective action is required by the operator or the electronic system.
The HPV-02 E5 has two switching solenoids and thus sets the pump to either neutral or maximum swash angle of any direction.

Dimensions. HPV-HPR-02 multiple pumps
Multiple pumps are created by combining individual pump units in series, with the pumps arranged by capacity. Positioning the
gear pump(s) at the end of the unit ensures optimum space utilization, output allocation and load distribution. The following table
is based on the gear pump acting as charge pump for the HPV-02 variable pump.
